Combining Multiple Units Combining Multiple Units Combining Multiple Units Combining Multiple Units
You may need to combine two or more units from different categories.
Note: Create a user-defined unit for frequently used combinations.
For example, suppose you want to enter a
velocity in meters per second. In the UNITS
dialog box, however, the
Velocity category
does not contain this unit.
You can enter meters per second by
combining
_m and _s from the Length and
Time categories, respectively.

and _s. There is no
pre-defined m/_s unit.
